EduSquares OTaaS — Online Testing as a Service

01 · The promise

You own the exam. We own the risk of running it.

Setting a paper is the easy part. Delivering it to tens of thousands of candidates — securely, simultaneously, online and offline, then evaluating and publishing results — is where institutions get burned. OTaaS is the operating layer that makes that a non-event.

One platform, pedagogy-neutral, proven from a single classroom quiz to a three-lakh-candidate national admission test.

A

Built for the stakes

Admission tests, semester exams, scholarship rounds, certification — where a dropped session or a leaked paper is not an option.

B

Built for the scale

Serverless on AWS. Load-tested to 50,000 concurrent candidates; run in production down to sub-1 Mbps candidate bandwidth.

C

Built for integrity

Lockdown browser, AI proctoring, encrypted twin-password paper distribution, full audit trail and credibility report on every session.

02 · Proof at scale

Twenty years, measured in outcomes.

Not a pilot. A production platform that leading institutions have leaned on for two decades.

03 · How it works

One lifecycle, from question to grade card.

A governed workflow with checks and balances at every stage — the same engine whether the test runs in a browser, on a tablet, on an offline LAN, or on printed paper.

01

Author

Bulk-import from DocX & Excel — equations, images, 16+ item types. Tag by topic, difficulty & competency; lock after proof-reading.

02

Publish

Generate papers by rule from the bank. SME review before release. Multi-format: DocX for offline, browser & mobile for online.

03

Deliver

World-class test engine. Online, offline, or LAN with no internet. Decoupled players let you add layouts & marking schemes fast.

04

Proctor

Lockdown browser, AI webcam monitoring, real-time fraud detection. Always working behind the scenes.integrity

05

Evaluate

Collect MCQs and handwritten scans alike. Digital Valuation routes to evaluators, scores, reviews & handles re-valuation.

06

Results

Analytics profile strengths & weaknesses; recommend content. Grade cards, SGPA/CGPA, and write-back to your ERP.

What you're looking at

The subjective-exam pipeline end to end: student scans at home, evaluator scores on-screen.

Integrity you can show an exam board — filmstrip evidence per candidate, not a checkbox.

The same engine behind a university semester exam and a coaching-centre mock test.

05 · Where we're different

The capabilities buyers can't stitch together elsewhere.

Anyone can serve an MCQ in a browser. These are the hard problems we've already solved in production.

Zero-internet exams

Exams on a LAN

A local server syncs the test in from the cloud, runs the exam entirely offline with 50 universal fallback logins, then syncs responses back out. Conduct national-grade tests where broadband can't be trusted.

Proven — Kota, sub-1 Mbps

Paper security

Twin-password distribution

Papers are set centrally and reach the centre encrypted, 30 minutes before start. Decryption needs two passwords — one held by the invigilator, one by the centre in-charge. No single point of leak.

Offline high-stakes

Subjective at scale

Digital Valuation System

Students scan & upload handwritten answer scripts from a phone within 10 minutes of finishing. DVS routes to the right evaluator, scores, reviews, finalises — and handles challenges & re-valuation.

Theory + practical

Anti-cheating

Real-time proctoring layer

Facial, device & body detection running live behind a lockdown browser that blocks every other window. Every session ends with an audit trail and a credibility report.

AI-backed

Architecture

Decoupled test players

Presentation is separated from the question data model, so new item types and marking schemes ship in days, not releases — and several players & marking schemes can coexist on one test.

6+ patterns · 16+ item types

Integration

Your ERP, our engine

SSO against your in-house system, real-time anonymised harvesting via JWT, results written straight back — with no PII crossing the boundary. xAPI-compliant interfaces throughout.

Anonymised · SSO

06 · Proof in the field
